The Riga Metro ((ラトビア語:Rīgas metro)) was a planned metro system in Riga, Latvia, during the time of the Soviet Union. Three lines with a total of 33 stations were planned to be built by 2021, however in the late 1980s, during the Singing Revolution, the whole project met with opposition and combined with the fall of the Soviet Union, construction, which was planned to begin in 1990, never took place. The population of the city has been declining due to emigration and negative population growth rate since 1990, making the prospects of a full metro system, even with EU funding, unrealistic in the near future. In fact, after the fall of the Soviet Union, possible construction of the metro system has even not been publicly discussed. ==History== The idea of the Riga Metro emerged in the mid 1970s, when city planners were examining how to integrate traffic systems into the capital. Several concepts were proposed, including the reconstruction of the city's railway or the installation of high-speed tram lines. However, officials regarded both proposals as inefficient. The most pressing issue was that Riga's population was rising quickly and was expected to eventually surpass one million, the requirement for constructing a metro in the Soviet Union. The Metrogiprotrans institute in Moscow was to design the layout of the metro system, work out the economic planning, and develop the detailed design of the project itself. The technical and economic basis of the project was to be completed by 1978. Another three years were scheduled for further elaboration of the project, with another nine years for the construction of the first eight metro stations. According to this plan, the first underground line was supposed to be opened in 1990. However, the development process faced continued delays, resulting in the technical and economic planning of the project being finished two years late, in 1980. A further five year delay followed, stalling construction work of the metro line and stations, which could not begin before the all preparation work was finished. Due to hard geological condition of soils the design of first section in 1984 was redirected to the Lenmetroproekt institute in Leningrad, more experienced in similar condition of metro in this city, resulting the opening date of Riga metro was rescheduled to 1997 at the earliest. Art-decor design of interior of stations was given to local architects that had an experience already after a development of Rizhskaya station of Moscow Metro. In 1986 the plan-general of metro system was updated to include three lines instead of two. Despite continued delays, the project phase of the first section was completed in 1989, its preparation for build phase started at 1986 while a construction phase would to be in 1990, and the opening date planned for 2000–2002. At the end of the 1980s, the project began to receive strong criticism, and, as a result of public dissatisfaction combined with the fall of the Soviet Union, the planned construction during the 1990s never began. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「The Riga Metro ((ラトビア語:Rīgas metro)) was a planned metro system in Riga, Latvia, during the time of the Soviet Union.
